## Description

Privacy Badger is a powerful Chrome extension developed by the Electronic Frontier Foundation (EFF) that automatically learns to detect and block hidden trackers on websites. It enhances your online privacy by sending the Global Privacy Control signal to opt you out of data sharing and selling, and the Do Not Track signal to request companies not to track your activity. If these signals are ignored, Privacy Badger proactively blocks the offending trackers.

Beyond blocking, Privacy Badger also replaces functional trackers like video players and comment widgets with click-to-activate placeholders, ensuring usability without compromising privacy. It actively removes outgoing link click tracking on major platforms such as Facebook and Google, with continuous updates to bolster user privacy protections. To learn more, check out the FAQ on [Privacy Badger's homepage](https://privacybadger.org/#faq). This extension is essential for users wanting to reclaim control over their online privacy effortlessly.
